Leslie Mann, who stars in her husband's Judd Apatow's comedy This Is 40, says that while she acts like aging doesn't bother her, looks can be deceiving. In fact, it's totally getting under her skin.

"I had a nervous breakdown. I look at myself and things look different. My skin looks different. My elbows, I have weird skin on my elbows I never had before. I have more wrinkles," sighs Mann, who turned 40 this year.
